Why don all the recipes liquid use 2 cups for a small batch and 4 for a large?
Flavor. Sometimes adding a 1/4 of a cup of something instead of a couple tablespoons will overpower the other flavors instead of enhancing the shot. Triple Sec in particular. It’s a really strong bitter orange flavor that can overwhelm delicate flavored liquors and many gelatine flavors. Ease of measurments. I imagine most of us don’t want to make shots with all the flavors divided into tablespoons and teaspoons. If you want your batch of Jell-O shooters to have 2 cups of liquid (or 4 cups if it a large batch), you could measure all the cool liquids together and top it off with water or a flavorless liquor, like vodka or everclear.
